hi, 5 weeks to sva, do not want to cut hole in bonnet for air filter, am using pieburgh carb at present, only 25 m/m between air filter mounting and bonnet face, looked into shorter carb, having no joy, any ideas, thanks. my engine at present is a cvh not pinto, do not know how to change my intro

I left my air filter off for the sva, no issues. Cut the hole later and fitted the air filters.

Should be ok to just leave it off

Simular problem with my CVH, left filter off. I have also had the inlet manifold adjusted to put it at a slight angle gains about 1cm.. I plan to put a remote filter on latter..

No major problem leaving it off for such a short period of time. Just be aware that you'll have to re-tune it afterwards when you put the filter on. Certainly worth doing something about it as unless you're really lucky and the bonnet at 25mm is acting as a pulse plate you'll be strangling the engine....
